Abstract: 754,715. Cam mechanism. RUSHTON, G. W. Feb. 7, 1955 [Feb. 6, 1954], No. 3542/54. Class 80(3) In a cam mechanism wherein a follower arm b, Fig. 4, carrying a rotatable camengaging runner b<SP>2</SP> is reciprocated by engagement with a double helical groove a<SP>1</SP>, a<SP>2</SP>, Fig. 2, in the surface of a rotating cylinder, the follower b also carries a pivotal diamond-shaped slide b<SP>1</SP> which engages narrow portions in the bottom of the groove in the neighbourhood of the cross-over point a to ensure that the follower remains in the same groove at this point. The narrow portions are discontinued adjacent the points where the helices change direction (see Fig. 1) so that the runner b<SP>2</SP> may effect reversal of the follower without interference from the slide b<SP>1</SP>. The positions of the runner b<SP>2</SP> and slide b<SP>1</SP> on the follower may be interchanged, in which case the narrow portions are formed in the top of the grooves.

Filed: 1946-02-05
Abstract: 607,451. Shoe &c. stretchers. BEURDEN, F. F. VAN. Feb. 5, 1946, No. 3562. [Class 17(iii)] Apparatus for stretching shoes comprises a platform 2, rising away from the operator towards the rear and carrying a trolley 6, on which the sole of the shoe to be stretched is placed, a block 20 adjustable in guides 22 on its underside adjacent an opening 23 therein through which a screw spindle 19 may operate at an angle to press against the underside of the sole in the shank, a guide plate 13 adjustable by a screw spindle 12 against the heel end of the shoe to prevent heelward extension and to serve as a zero mark against which stretching may be measured, and a U-shaped piece 25 adjustable by a handwheel 26 to engage the breast face of the heel and prevent it tilting during stretching. Heel and toe last parts 4, .5 inserted in the shoe, which is placed on the platform 2 leg upwards, are forced apart by rotation of a handwheel 17 which moves the parallel legs 15, inserted between the parts 4, 5, in guides 16. A device for stretching the toe widthwise may be operated by the screw spindle 14. A roller 8 is adjustable by a screw spindle 7 to bear against a groove 10 in a block 11 fitted to the toe last part 5. The platform 2 may carry means for stretching both shoes of a pair, which if operated in turn, provides a means of determining the amount of stretch effected and any distortion from shape The toe last part 5 may be provided with means for laterally stretching the toe, if desired. The heel part 4 of the last may have nails 28 projecting on the underside to engage the insole of the shoe being stretched. In use tilt given to the shoe during operation of the stretching devices is corrected by the instep screw 19, and stretching pressure reapplied as necessary.

Title: Surface profile measuring apparatus
IPC: G01B11/30
Filed: 1976-01-29
Abstract: 1513611 Optical measurement of surface roughness BENDIX CORP 29 Jan 1976 [26 Feb 1975] 03564/76 Heading G1A In apparatus for measuring surface roughness of the type in which light from an illuminated spot 12 scanned across the surface 14 is received by two photo-detectors positioned differently with respect to the focal plane of an objective lens 26, a slit 40 is positioned in front of one of the detectors 36. This detector is positioned 7 cm from the focal plane 38 when the focal distance of lens 26 is 27 cm. This is said to maximize the linear dynamic range of the generated signals. A large area detector 34 generates electrical signals corresponding to the total illumination received from the spot 12. The ratio of the detector output signals is plotted against a scan position signal by a recorder 48, thus providing a profile of the surface. For surfaces in which the peaks and valleys of the roughness profile are aligned in one direction the aperture in screen 40 may be a slit (5 X 0À15 mm for example) and.the surface scanned in a direction normal to this alignment.

Title: Improvements in and relating to the manufacture and production of coloured artificial filaments, threads, bands and the like
IPC: D01F2/16
Filed: 1934-02-08
Abstract: In the production of coloured threads, filaments, bands, and the like, by spinning viscose containing a leuco vat colouring matter, a glycol ether is added to the vat dye, either before or after its conversion into the leuco compound.  The glycol ether may be a methyl, ethyl, or butyl ether of mono-ethylene or diethylene glycol. The addition of a glycol ether prevents crystallization of the leuco compound when present in high concentration in portions of the viscose which are subsequently fed to the main body of spinning solution.  In an example, Caledon Blue R.C. paste is mixed with water and caustic soda.  The leuco compound is formed by warming with sodium hydrosulphite. Diethylene glycol mono normal butyl ether is added and, after cooling, the mixture is stirred into ripened viscose.  The solution is spun into a bath of sulphuric acid, sodium sulphate, zinc sulphate, and glucose.  The filaments are desulphurized and bleached.  They are of a level and fast blue colour.  In another p  example, Caledon Brown R paste is mixed with water and caustic soda and converted into the leuco compound by warming with sodium hydrosulphite.  Diethylene glycol mono ethyl ether is added, and the mixture is cooled and stirred with viscose. The solution is either spun direct or mixed with a main body of viscose which is then spun to form filaments.  Specifications 181,902 and 290,693, [both in Class 15 (ii)], are referred to.

The air space above the liquid in the chamber 15 communicates with the atmosphere through apertures 34, 35 arranged respectively in the chamber and in the cap 29 supporting the tube 21 and conduit 27. In operation, fluctuations of the level of liquid in the tank 11 produce a variation in the pressure of the air trapped in the chamber 14 and a displacement of liquid between the chambers 14, 15, thus varying the air pressure in the tube 21 and conduit 27 and operating the indicator. The later comprises a central tubular body 36, Fig. 3, connected to the conduit 27 and surrounded by an outer transparent tube 41, the lower parts of the tubes being in communication and containing liquid the level of which in the outer tube 41 gives an indication of the amount of liquid in the tank 11.
